An Efficient Approach for Analyzing Shielding Effectiveness of Enclosure With Connected Accessory Based on Equivalent Dipole Modeling
Bibliographic record
Abstract
The analysis of the enclosure's shielding effectiveness (SE) is an important work in the electronic device's electromagnetic compatibility problem. Almost all devices cannot work without connected accessory including cables and electronic connectors. Except for apertures and seams on the enclosure, the connected accessory is also a leakage path for electromagnetic power. For the SE problem of enclosure with connected accessory, a hybrid numerical analysis method of the partial element equivalent circuit (PEEC) and the method of moment (MoM) are proposed. PEEC is used to model the connected accessory. Based on energy conservation, the cable-connector is replaced by an equivalent dipole that has similar electromagnetic radiation properties. The equivalent dipole is added to the model of enclosure, which is analyzed by the MoM. Two experiments are presented to verify the proposed hybrid approach. The test results are in good agreement with the simulated results. This hybrid method not only could be used to calculate the SE of the cable-enclosure system, but also has the potentiality to apply to the signal integrity of printed circuit boards in enclosures.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
